作业：C++利用栈实现的计算器

通过把后缀表达式转为逆波兰式并压入栈中，再一一出栈完成运算，只支持整型数的运算//实现计算功能的模块（头文件Lunching.h）#include#include#include"Myblade.h"#include"MyRapier.h"using namespace std;//My target is a caculater that prove long numbers with space in them to caculate//At least can recognize two different prackets//ok then MOVEclass TNode{public:char Data;TNode *Next;};class Calculating{private:Stack OPER;NStack NUMB;public:float TheCaculater();int procede(char a, char b);float Operate(int a, int b, char Operater);void NmberAnalyze(char First, int &Number, char &Operater);void RPNTransfrom();void OutPut();void DestroyAll();};int Calculating::procede(char Top, char Ele){if(OPER.StackEmpty() == 1)return 1;int Fl = -1;int X = 0, Y = 0;int Priority[4][4] = { {1, 1, 0, 0},{1, 1, 0, 0},{1, 1, 1, 1},{1, 1, 1, 1}};if(Top == '+')X = 0;else if(Top == '-')X = 1;else if(Top == '*')X = 2;else if(Top == '/')X = 3;else{return 1;}if(Ele == '+')Y = 0;else if(Ele == '-')Y = 1;else if(Ele == '*')Y = 2;else if(Ele == '/')Y = 3;else if(Ele == '(')return 1;else{return 1;}Fl = Priority[X][Y];return Fl;};float Calculating::Operate(int a, int b, char Operater){float OP = 0;float OA = (float)a;float OB = (float)b;if(Operater == '+'){OP = OA + OB;}else if(Operater == '-'){OP = OA -
